Detailed Description of the Invention

[0008] Hereinafter, a hair holding device of the present invention will be described with reference to the drawings with regard to a first embodiment which is a preferred embodiment thereof.

As shown in FIGS. 1 (a) to 3, the hair holder 1 of the present embodiment has a cylindrical shape configured to allow the hair bundle to pass from the opening 21 at one end toward the opening 22 at the other end. It is a hair holder made of body 2. Cylindrical body 2 is formed of a single-sided sheet 23A positioned on the inner side when rolled up and an outer-side sheet 23B positioned on the outer side when rolled up, and the single-sided sheets 23A and Z or the other-sided sheet 23B Is 0.4 mN 'm or more. The opening 21 at one end of the tubular body 2 is provided with a stress relaxation means for relaxing the stress applied to the hair bundle inserted into the opening 21.

[0009] The hair holder 1 of the present embodiment will be described in further detail. As shown in FIGS. 1 (a) to 1 (c), the hair holder 1 of the present embodiment is configured mainly with a cylindrical body 2, an extending portion 4, and a winding piece 3.

As shown in FIGS. 1 (a) to 1 (c), the cylindrical body 2 has a hair bundle H (see FIGS. 4 (a) to 4) from the opening 21 at one end to the opening 22 at the other end. (Refer to (c)), and has a flat shape. Cylindrical body 2 is formed by joining one side sheet 23A and the other side sheet 23B. Has been. Specifically, the cylindrical body 2 is formed by joining a one-sided sheet 23A and another-sided sheet 23B at both longitudinal side portions 24, 24 thereof. The single-sided sheet 23A is a sheet positioned on the inner side when rolled up, and the other-sided sheet 23B is a sheet positioned on the outer side when rolled up.

[0010] The size of the cylindrical body 2 is a force that is appropriately set according to the length of the hair, the place where the hair is desired to be worn, and the amount of the hair bundle to be inserted. Preferably, the length is 50 to 350 mm, and the width is 20 to : LOOmm

[0011] As a forming material of the base material sheet 23 (in the description common to the surface sheet 23A and the other surface sheet 23B, the expression "base material sheet 23" is used), for example, a non-woven fabric (polyethylene non-woven fabric) , Polyethylene terephthalate nonwoven fabric, etc.), woven fabric, mesh sheet, porous or non-porous resin film (polyethylene film, polyethylene terephthalate film, etc.), paper, polymer material sheet, rubber sheet, or composites thereof Is mentioned. The thickness of the base sheet 23 is preferably 30 to 500 μm.

[0012] The other surface sheet 23B is provided with a plurality of slits 26 extending in the width direction and spaced apart in the longitudinal direction. The slit 26 is formed mainly for improving the extensibility of the other side sheet 23B. In the present embodiment, both end portions 26A of the slit 26 are formed into a circular shape by punching, and the central portion 26B other than the both end portions 26A is formed by cutting with a thin blade.

[0013] In addition, an engagement sheet piece 52 that can be engaged with a winding portion 51 (described later) is provided on the opening 21 side at one end of the other surface sheet 23B. A slit 26 is also formed in the engagement sheet piece 52, and the other side sheet 23B is a belt-like piece as a whole of the force divided by these slits 26. As the engagement sheet piece 52, various kinds can be used as long as the engagement sheet piece 52 can be engaged with the winding portion 51. For example, a nonwoven fabric is used. The engagement sheet piece 52 preferably has a certain length because the engagement position with the winding portion 51 changes in the longitudinal direction of the tubular body 2 depending on the diameter of the tubular body 2. For example, the length is 2-15cm.

In the present embodiment, the single-sided sheet 23A is made of a polyester-based nonwoven fabric having a basis weight of 150 gZm ^{2, and} no slit 26 is formed. The other side sheet 23B has a polyester nonwoven fabric having a basis weight of 50 gZm ² and has ten slits 26 formed therein. [0015] One or both of the one-sided sheet 23A and the other-sided sheet 23B has a Taber stiffness of 0.4 m N'm or more, preferably lmN'm or more. If the taber has such a stiffness, the cylindrical body 2 into which the hair bundle H is inserted can be easily wound up in a beautiful winding shape without using a rod (rod). it can.

When the Taber stiffness of either one of the base sheet 23 is 0.4 mN'm or more, the Taber stiffness of the one-sided sheet 23A is preferably 0.4 mN'm or more. It is more preferable that the Taber stiffness of both base sheet 23 is 0.4 mN'm or more.

The upper limit value of the Taber stiffness is lOmN ′ m from the viewpoint of easy winding of the cylindrical body 2.

The “Taber stiffness” is a taper stiffness measured by the “stiffness test method” defined in JIS P8125.

[0016] As shown in Fig. 1 (b) and Fig. 1 (c), on the outer surface of both side portions 24 of the other surface sheet 23B, a belt-like reinforcing member having a width substantially equal to the width of the joint portion (seal portion). B and B are joined together. By joining the reinforcing member B to the other surface sheet 23B, the taber stiffness of the entire tubular body 2 is improved. However, since the reinforcing member B is provided only on the both side portions 24 of the cylindrical body 2, the ease of opening the opening 21 at one end of the cylindrical body 2 is not particularly reduced. The insertability of the hair bundle H is not particularly reduced.

[0017] The cylindrical body 2 is creased so that the state of being rolled up in a predetermined shape is maintained.

Specifically, as shown in FIG. 2, the cylindrical body 2 is crushed by a predetermined means so that the state of being rolled up with the other surface sheet 23B facing outward is maintained. Therefore, when the cylindrical body 2 is stretched in the longitudinal direction as shown in FIGS. 1 (a) to 1 (c) and the state force is released, as shown in FIG. It is now possible to voluntarily roll up into a state of being rolled up! The hair holder 1 composed of such a cylindrical body 2 has an advantage that a winding operation is unnecessary and a means for holding the winding form such as a clip is unnecessary.

In order to attach the cylindrical body 2, for example, the cylindrical body 2 is rolled up, the rolled form is maintained by a predetermined means, and the cylindrical body 2 is heated to a predetermined temperature under the state. do it. [0018] As shown in Fig. 1 (a) to Fig. 1 (c), the end of the opening 21 at one end of the cylindrical body 2 has a longitudinal direction (hair) from the one-surface sheet 23A. An extending portion 4 extending in the direction opposite to the direction in which the bundle H is inserted is provided. In the present embodiment, the single-sided sheet 23A and the extending portion 4 are formed integrally.

[0019] On the opposite side of the extended portion 4 from the other sheet 23B, a winding portion 51 is provided. The winding part 51 can be engaged with the engagement sheet piece 52. By engaging the winding part 51 with the engagement sheet piece 52 in the rolled up cylindrical body 2, the winding part 51 of the cylindrical body 2 can be engaged.ている It can maintain the lifted state. As the winding part 51, for example, a male member of a mechanical fastener can be used.

The winding part 51 can be engaged with the other sheet 23B depending on the combination with the material of the other sheet 23B.

[0020] Both side portions 24 near the opening 22 at the other end of the cylindrical body 2 are respectively provided with winding pieces 3 and 3 extending from the both side portions 24 in the width direction of the cylindrical body 2. . The winding piece 3 has a semicircular arc shape.

Each of the one-sided sheet 23A, the other-sided sheet 23B, and the reinforcing member B has an extending region corresponding to the tightening piece 3. Therefore, the extension of the one-sided sheet 23A, the other-sided sheet 23B, and the reinforcing member B is extended. A winding piece 3 is formed from the laminate in the exit region.

Note that the formation method, shape, size, thickness, arrangement, and the like of the winding piece 3 are appropriately set.

[0021] The opening 21 at one end of the cylindrical body 2 is provided with stress relaxation means for relaxing the stress applied to the hair bundle H inserted into the opening 21. The stress relieving means in this embodiment is a small flap 61 that is joined to the one-sided sheet 23A and is provided in the opening 21 at one end of the other-sided sheet 23B.

[0022] The flap 61 also has a partial region force on the opening 21 side at one end of the other surface sheet 23B, and is not joined to the one surface sheet 23A and the extending portion 4. The length of the flap 61 (length in the longitudinal direction of the cylindrical body 2) is appropriately set, but is preferably 1 to 30 mm, and more preferably 5 to 15 mm. Therefore, the flap 61 is turned up from the one-sided sheet 23A, with the line 61A connecting the ends on the one end opening 21 side at the joint portion of the both side portions 24 of the cylindrical body 2 as the base end. Yes. The shape of the flap 61 is the same as that of the flap 61 in the first embodiment. For example, a trapezoidal shape, a semi-elliptical arc shape, or a semi-arc shape may be used.

The flap 61 is provided with a cut 62 extending in the longitudinal direction of the cylindrical body 2. The length, number, interval, etc. of the breaks 62 are set as appropriate. The length of the cut line 62 can be, for example, a length exceeding the line 61 A from one end of the flap 61, specifically, 2 to 40 mm. The number of cuts 62 can be, for example, 1 to 8. The interval between the cut lines 62 can be set to 5 to 20 mm, for example.

[0024] Next, as one usage of the first embodiment of the hair holding device of the present invention, a case where curling is directly applied to hair (hair) by perm treatment is shown in Figs. Explain with reference to c).

First, depending on the amount of the hair bundle H and the curl shape to be obtained, the hair holder 1 composed of the cylindrical body 2 having an appropriate length and width is used, and the opening at one end of the cylindrical body 2 is used. 21 is opened in an elliptical shape, and the hair bundle H is inserted into the opening 21 at one end, as shown in FIG. 4 (a).

[0025] After inserting the hair bundle H through the cylindrical body 2, as shown in Fig. 4 (a) and Fig. 4 (b), the cylindrical body 2 is moved from the opening 22 side at the other end to the one-sided sheet. Wind up with 23A inside. In the present embodiment, the cylindrical body 2 is wound up so that the state of being rolled up in a predetermined shape is maintained, so that the cylindrical body 2 rolls up spontaneously. When the cylindrical body 2 is wound up, the cylindrical body 2 can be reliably wound up as necessary. After winding up the cylindrical body 2, as shown in FIG. 4 (c), the winding portion 51 and the engagement sheet piece 52 are engaged. As a result, the cylindrical body 2 is fixed in a wound state with a predetermined diameter.

[0026] Thereafter, a hair treatment agent for the outer force perm of the cylindrical body 2 is applied to the hair bundle H. After a predetermined time, the hair bundle H is removed from the cylindrical body 2, and the perm treatment is completed by washing the hair. When the hair bundle H is inserted from the opening 21 at one end of the cylindrical body 2, the opening 21 may be opened in a perfect circle in order to insert the hair bundle H more smoothly. When a hair insertion tool (not shown) provided with a hook portion capable of hooking the hair bundle H is used, the hair bundle H can be easily inserted into the tubular body 2. The tip of the hair bundle H may protrude from the opening 22 at the other end of the cylindrical body 2.

[0027] By the way, when the tubular body 2 through which the hair bundle H is inserted is wound with the face sheet 23A inside, the hair bundle H inserted through the tubular body 2 and wound up is linear. Try to restore to The force in the bending direction is applied to the hair bundle H near the opening 21 at one end of the cylindrical body 2 by the force of the bending.

Thus, according to the hair holder 1 of the present embodiment, the opening 21 at one end of the cylindrical body 2 is used as a stress relaxation means for relaxing the stress applied to the hair bundle H inserted into the opening 21. A flap 61 is provided in the region on the opening 21 side at one end of the other surface sheet 23B, which is joined to the one surface sheet 23A.

Therefore, as shown in FIG. 5, the flap 61 is turned up in the direction in which the force of the surface sheet 23A is also separated, and the stress applied to the hair bundle H in the vicinity of the opening 21 at one end of the cylindrical body 2 is relieved. The When the flap 61 is pressed in the direction in which the flap 61 is turned up by the hair bundle H, the cylindrical body 2 is pressed in the direction of the arrow D shown in FIG. Also from this point, the stress applied to the hair bundle H in the vicinity of the opening 21 at one end of the cylindrical body 2 is relieved. As a result, even when a large amount of hair bundle H is inserted into cylindrical body 2 or when damaged hair bundle H is rolled up, the hair inserted into opening 21 at one end of tubular body 2 Bundle H is hard to break. In particular, in the hair holder 1 of the present embodiment, since the cut 61 is formed in the flap 61, the flap 61 is turned up while spreading in the width direction of the cylindrical body 2, and the stress applied to the hair bundle H is further alleviated. It is easy to be done.

[0029] Next, second to seventh embodiments, which are other embodiments of the hair holding device of the present invention, will be described. The second embodiment to the seventh embodiment will be described with a focus on differences from the first embodiment, and the description of the first embodiment will be appropriately applied to points that are not particularly described. The second to seventh embodiments are also used in the same manner as the first embodiment, and the same effects as the first embodiment are achieved.

[0030] In the hair holding device of the second embodiment, the flap 61 generates a restoring force toward the surface sheet 23A (as shown in FIG. 6, the end on the opening 21 side of one end). The restoring force is generated in the direction of the arrow shown in Fig. 6 (b) with the line 61A connecting the bases as the base end). Other configurations are the same as those of the first embodiment. In the second embodiment, as shown in FIGS. 6 (a) and 6 (b), the reinforcing member B is joined to both sides of the flap 61. Due to the rigidity of the reinforcing member B, the flap 61 The configuration is designed to generate a restoring force toward the face sheet 23A. Reinforcing members B on both sides of flap 61 are on both sides of single-sided sheet 23A 2 The four reinforcing members B are extended.

In addition to the configuration in which the reinforcing member B is provided on the flap 61, the configuration in which the flap 61 generates a restoring force toward the surface sheet 23A, for example, the flap 61 is directed toward the one-side sheet 23A. This can be realized by forming a shape memory material force in which the shape is memorized in the direction in which the restoring force is generated.

[0031] As described above, the hair holder of the second embodiment has a configuration in which the flap 61 generates a restoring force toward the surface sheet 23A in addition to the configuration of the hair holder of the first embodiment. It is equipped with. Therefore, in addition to the same effects as those of the first embodiment, the following effects are also exhibited. Specifically, even if the hair holder is used repeatedly, the flap 61 is difficult to sag. The flaps 61 that are apt to become obstructive when using the hair retainer are easily inconvenient to handle, and also make it difficult for the flaps 61 to relieve stress (effects to relieve the stress applied to the hair bundle). Therefore, according to flap 61, which has a restoring force toward single-sided sheet 23A and is difficult to sag, it is unlikely to interfere with the use of the hair retainer, and is less likely to be inconvenient to handle. continue.

If the restoring force of the flap 61 is too strong, the stress relaxation effect, which is the primary object of the present invention, may be hindered. Therefore, it is preferable to set the restoring force of the flap 61 within a range that does not obstruct the stress relaxation effect.

[0032] In the hair holder of the third embodiment, as shown in Figs. 7 (a) and 7 (b), the stress relaxation means is provided in the bulge provided in the opening 21 at one end of the other surface sheet 23B. It is outing. The bulging portion is formed by projecting a region on the opening 21 side at one end of the other surface sheet 23B toward the direction in which the one surface sheet 23A is separated. Such a shape is formed, for example, by plastically deforming the region on the opening 21 side at one end including the edge 25 in the other surface sheet 23B into a shape that is turned up in a direction away from the one surface sheet 23A. be able to. The overhanging amount L1 of the other side sheet 23B is appropriately set, but is preferably 5 to 30 mm.

[0033] According to the hair holder of the third embodiment configured as described above, when the tubular body 2 into which the hair bundle H is inserted is rolled up, the vicinity of the opening 21 at one end of the tubular body 2 Since the hair bundle H can move to the other side sheet 23B forming the bulging portion, the stress applied to the hair bundle H Is alleviated. Therefore, the same effect as the hair holder of the first embodiment is exhibited.

In the hair holder of the fourth embodiment, as shown in FIG. 8, the stress relaxation means is a notch 25 provided on the opening 21 side at one end of the other surface sheet 23B. The notch 25 has a concave shape toward the opening 22 at the other end. Examples of the shape of the notch 25 include a semi-elliptical shape and a semi-circular shape. The notch amount L2 is appropriately set, but is preferably 5 to 30 mm.

[0035] According to the hair holder of the fourth embodiment configured as described above, when the tubular body 2 into which the hair bundle H is inserted is rolled up, in the vicinity of the opening 21 at one end of the tubular body 2 Since the hair bundle H can move to the edge side of the notch 25, the stress applied to the hair bundle H is relieved. Therefore, the same effect as the hair holder of the first embodiment is exhibited.

In the hair holder of the fifth embodiment, as shown in FIG. 9, the stress relaxation means is a low-load extension material (at a low load) provided in the opening 21 at one end of the other surface sheet 23B. Elongating material) 63. The length of the low-load extension material 63 (the length in the longitudinal direction of the cylindrical body 2) is an appropriately set force, preferably 10 to 50 mm. “Low load elongation material” refers to a material with an elongation of 5% or more under 5N load. Examples of the low-load stretch material 63 include polyethylene nonwoven fabric, polypropylene fabric nonwoven fabric, polyester nonwoven fabric, woven fabric produced from rubber yarn force, nonwoven fabric produced from rubber fiber cage, and the like.

[0037] Part (part closer to the opening 21 at one end; see Fig. 9) of the low-load stretchable material 63 is joined to the one-sided sheet 23A! /, Na! /, And part E exists. ! /

When the region on the opening 21 side at one end of the other sheet 23B is composed of the low-load stretch material 63, the low-load stretch material 63 and a material that does not stretch under a low load are joined together in the longitudinal direction. If these two materials are overlapped with each other so as to be continuous in the longitudinal direction without being joined, they can be arranged.

[0038] According to the hair holder of the fifth embodiment configured as described above, when the tubular body 2 through which the hair bundle H is inserted is wound up, the vicinity of the opening 21 at one end of the tubular body 2 The hair bundle H can press the low-load elongation material 63 and stretch it to move away from the one-sided sheet 23A, so that the stress applied to the hair bundle H is relieved. Therefore, the same effect as the hair holder of the first embodiment is produced. In the hair holder of the sixth embodiment, as shown in FIG. 10 (a), the stress relaxation means is the width of the cylindrical body 2 provided in the opening 21 at one end of the other surface sheet 23B. Folding direction 64. The amount of folding in the width direction may be appropriately set according to the required amount of stress relaxation.

The other side sheet 23B folded as shown in FIG. 10 (a) has, for example, a region 64 ′ on the side that becomes the opening 21 at one end formed in a pentagonal shape as shown in FIG. 10 (b). It can be formed by using a material and folding it with two fold lines 64A, 64A arranged in a V shape so that the region 64 ′ is rectangular. In this state, when the one-sided sheet 23A and the other-sided sheet 23B are joined in the region that becomes the both side portions 24 of the cylindrical body 2, the cylindrical body 2 is formed.

[0040] According to the hair holder of the sixth embodiment configured as described above, when the tubular body 2 into which the hair bundle H is inserted is rolled up, the vicinity of the opening 21 at one end of the tubular body 2 The hair bundle H can press the fold 64 on the opening 21 side of the one end, expand it, and move the single-sided sheet 23A force in the direction of separating, so the stress applied to the hair bundle H is relieved. The Therefore, the same effect as the hair holder of the first embodiment is produced.

In the sixth embodiment, the stress relaxation means may be a slack (not shown) in the width direction of the cylindrical body 2 provided on the opening 21 side at one end of the other sheet 23B.

[0041] In the hair holder of the seventh embodiment, as shown in FIGS. 11 (a) and 11 (b), the stress relaxation means is provided in the opening 21 at one end of the other surface sheet 23B. A portion 65A provided from the opening portion 21 at one end and extending from the opening portion 21 at one end is a curved plate-like member 65 that is curved from the surface sheet 23A toward the other surface sheet 23B. .

As shown in FIG. 11 (a), the curved plate member 65 in the present embodiment is also a plate member having a substantially triangular shape in a front view and a curved upper end portion in a side view. The curved plate member 65 is made of, for example, a resin film or metal. As shown in FIG. 11 (b), the curved plate-like member 65 is joined to the inner surface side of the opening 21 at one end of the other surface sheet 23B, and a portion 65A extending from the opening 21 at one end is a surface. The sheet 23A curves toward the other sheet 23B.

[0042] According to the hair holder of the seventh embodiment configured as described above, when the tubular body 2 through which the hair bundle H is inserted is wound up, the vicinity of the opening 21 at one end of the tubular body 2 Hair Bundle H is Bay Since the curved plate member 65 can move to the extended portion 65A side, the stress applied to the hair bundle H is relieved. Therefore, the same effect as the hair holder of the first embodiment is produced.

[0043] As described above, the curved plate-like member 65 may be joined to the other surface sheet 23B of the cylindrical body 2, but may not be joined. The curved plate-like member 65 that is not joined to the other surface sheet 23B is installed in the opening 21 at one end of the tubular body 2 when the hair bundle H is inserted from the opening 21 at one end of the tubular body 2. Used. After the curved plate member 65 is installed in this way, if the hair bundle H is inserted between the curved plate member 65 and the one-sided sheet 23A, the curved plate-like member 65 is joined to the other-side sheet 23B. The effect is the same as that of a hair holder [see Fig. 11 (b)].

Alternatively, after the hair bundle H is wound up using the cylindrical body 2, the curved plate member 65 is still inserted into the other sheet 23B even if the curved plate member 65 is inserted between the other sheet 23B and the hair bundle. The same effect as that of the hair holding tool joined to [see Fig. 11 (b)] is obtained.

[0044] The hair retainer of the present invention can be appropriately modified as long as it does not depart from the spirit of the present invention without being limited to the above-described embodiment.

The stress relieving means is not limited to each stress relieving means in the embodiment as long as it relieves stress applied to the hair bundle inserted into the opening at one end of the cylindrical body. The single-sided sheet 23A and the other-sided sheet 23B may be formed with a single sheet material force. In that case, the cylindrical body 2 may be formed by folding the sheet material in the center in the width direction as a folding line.

[0045] Further, the hair holder of the present invention is not limited to the case of curling hair by perm treatment, and after winding the hair bundle, it is heat-treated with a dryer or the like, or the dried hair is in a wound state. It can also be applied to the case of curling hair by holding it or holding wet hair in a wound state and allowing it to dry naturally.

Industrial applicability

[0046] According to the hair holder of the present invention, the hair is unlikely to break near the hair intake opening in the tubular body.
